BACKGROUND OF THE INVENTION

Embodiments of the present invention relate to a method and device that may be used to clean and/or sanitize an outer surface of the portion of a can or other drink or food container that will be opened and, more specifically, to a portable container cleaning apparatus for use with or without a sanitizing additive (e.g., chlorine, ethyl alcohol, etc.). Applying multiple soft bristles at the tip of an exemplary apparatus, used with or without sanitizing agents, a can/container may be cleaned and/or sanitized of certain hazardous and/or noxious materials and will be safe for consumption. As used herein, the term “sanitized” is not intended to be limited to a level of cleanliness amounting to “sterilized,” and should be read to include situations where a container is generally cleaner in some degree after use of embodiments of the apparatus disclosed herein than the container was before use of such embodiments.

Drink and food containers, such as cans, bottles, jars, Aseptic packages/pouches, etc. may sometimes be sanitized for consumers at the point of production and processing. In particular, metal packaging may provide an appreciable degree of protection from outside contaminants entering into a drink or food container. Once shipped from the production point and into storage and ultimately the consumer supply chain, some of the sanitation processes and procedures may be at risk in some circumstances, such as those related to the condition of the outside of such containers. Specifically, and for purposes of illustration only, beverage cans that have had the exterior of the top of the sealed can exposed in storage or in retail environments may, in some situations, have had contact with a multitude of contaminants and toxins found in such open environments, including pesticides, solvents, detergents, dust, and/or other caustic and dangerous or otherwise undesirable elements.

While a variety of devices and methods have been made and used to clean a portion of a container, it is believed that no one prior to the inventors has made or used a device or method as recited in the claims.

By way of example only, bristles and/or a cleaning member may be removable and/or replaceable in some fashion. For instance, in some embodiments (not depicted) a bristle base, with bristles extending therefrom, may be “snap fit” into a handle portion, and may be removable therefrom. Thus, if bristles become worn or dirty, etc., a user may remove the base that the undesirable bristles extend from, relative to the handle portion, and “snap” a new bristle base into the handle portion, with new bristles extending therefrom. Similar features and techniques may be used for a cleaning member that is provided with or in lieu of bristles. In other embodiments, a handle portion (or other portion) may house a plurality of bristle bases or cleaning members. A replacement bristle base (with replacement bristles extending therefrom) and/or a cleaning member may thus be immediately available for replacing a used bristle base (with used bristles extending therefrom) or used cleaning member. Furthermore, such a replacement bristle base and/or cleaning member may be spring-loaded, otherwise resiliently loaded or biased, or otherwise configured, such that a user merely has to remove a used set of bristles or cleaning member from the handle portion, and a replacement set of bristles or cleaning member “pops out,” gets pulled out, or otherwise appears, to take the place of the used bristles or cleaning member. It will be appreciated that this may be accomplished using a variety of structures, configurations, or techniques. Another merely illustrative example of a component that may be removable and/or replaceable may include a reservoir that contains a cleaning agent, to the extent that a cleaning agent is used. Other ways in which bristles, a cleaning member, and or any other component may be replaceable in any suitable fashion will be apparent to those of ordinary skill in the art.

Having shown and described various embodiments of the present invention, further adaptations of the methods and systems described herein may be accomplished by appropriate modifications by one of ordinary skill in the art without departing from the scope of the present invention. Several of such potential modifications have been mentioned, and others will be apparent to those skilled in the art.
